與大多數流行的 Web 服務如 twitter 通過開放 API 來提供數據一樣,它總是能夠知道如何解析 API 數據的各種傳送格式,包括JSON,XML 等等,實例代碼如下:
- $json_string='{"id":1,"name":"foo","email":"foo@foobar.com","interest":["wordpress","php"]} ';
- $obj=json_decode($json_string);
- echo $obj->name; //prints foo
- echo $obj->interest[1]; //prints php
PHP解析 XML 數據,實例代碼如下:
- $xml_string="<?xml version='1.0'?>
- <users>
- <user id='398'>
- <name>Foo</name>
- <email>foo@bar.com</name>
- </user>
- <user id='867'>
- <name>Foobar</name>
- <email>foobar@foo.com</name>
- </user>
- </users>";
- //load the xml string using simplexml
- $xml = simplexml_load_string($xml_string);
- //loop through the each node of user
- foreach ($xml->user as $user)
- {//開源代碼Vevb.com
- //access attribute
- echo $user['id'], ' ';
- //subnodes are accessed by -> operator
- echo $user->name, ' ';
- echo $user->email, '<br />';
- }
